“…The multilevel boost converter has been studied in several articles [51][52][53][54][55][56][57][58][59], with contributions that include their modeling and control [56][57][58][59]. Some works include the negative extension (instead of the positive) or both [51,55,57].…”

The increasing interest in renewable energy sources has brought attention to large voltage-gain dc–dc converters; among the different available solutions to perform a large voltage-gain conversion, this article presents an overview of non-isolated dc–dc converter topologies that utilize switched-capacitor circuits, i.e., diode-capacitors voltage multipliers. The review includes combinations of a traditional power stage with a diode-capacitor-based voltage multiplier, such as the multilevel boost converter. This article starts by reviewing switched-capacitor (SC) circuits, different topologies, and different types of charge exchange; it provides a straightforward analysis to understand the discharging losses. It then covers the multilevel boost converter and other topologies recently introduced to the state-of-the-art. Special attention is put on SC circuits with resonant charge interchange that have recently been probed to achieve very good efficiency. An additional contribution of the article is new proof of the discharging losses in resonant switched-capacitor circuits focused on the initial and final stored energy in capacitors, and this proof explains the relatively large efficiency obtained with SC resonant converters.

“…Among the non-isolated converters, boost, coupled inductor and tapped inductor types are widely used in EV applications. A 3-level bidirectional converter is used for a power management scheme with battery and fuel cell [5,6,7]. A multiphase coupled inductor bidirectional dc converter to offer fast transient response and to reduce inductor current ripple is proposed for EVs.…”

Escalating fuel prices and a keen attention to improve air quality have resulted in proliferation of pure electric and hybrid electric vehicles. Fuel savings and reduced carbon footprint are the main enablers for the choice of electric automobiles compared to the conventional vehicles with internal combustion engines. Availability of electric power sources such as lightweight battery packs also has promoted electric drive as a viable option. Both plug-in electric and hybrid vehicles necessitate new power train schemes ensuring safe and reliable operation. The DC -DC converters are the heart of an electric vehicle. They are used to convert the battery voltage to another level as required by the motor drive. Traditionally, most of the automakers use buck boost converter as it enables the bidirectional operation. This paper presents a comprehensive analysis of a dual way DC-DC converter namely split pi converter for an electric vehicle drive train system driving an inverter fed induction motor. The dual way converter investigated has numerous advantages such as inherent bidirectional capability, EMI reduction and reduction of the passive elements. Simulation results and experimental investigations based on a laboratory prototype are presented.

“…This limits the switching frequency and systems size [3]. Some voltage multiplier techniques were also introduced for a boost converter in order to increase the static gain with reduced switch voltage [4]. However, in order to further reduce the voltage stress of active switches as well as electromagnetic interference (EMI) [5,6], in this paper, a novel single-stage three-phase high step-up DC/DC converter topology is proposed and experimentally tested by a 100 V/110 W circuit prototype in 24 V-battery-powered micro DC-UPS to verify the feasibility.…”

A conventional battery-powered AC uninterruptible power supply (AC-UPS) that steps up low DC voltage to high DC voltage and cascades with the high frequency inverter is complicated in control and of low efficiency due to two-stage power conversion. This paper presents a threephase high step-up converter with a single-stage DC/DC power conversion suitable for micro DC-UPS applications. In this paper, the circuit operating theory and steady-state analysis of the proposed topology are first addressed then a 100 V/110 W circuit prototype is designed, built and applied in 24 Vbattery-powered micro DC-UPS for a 19 V/85 W laptop PC appliance. The feasibility and effectiveness of the proposed converter topology are confirmed with experimental results. The maximum conversion efficiency of the proposed converter is about 93.5%, and the overall efficiency of the designed system is high due to the losses in the power conversion process when reduced. Compared with the conventional AC-UPS, the proposed micro DC-UPS achieves potentially about 3% maximum energy savings.
